LM4041DYM3-1.2-TR

Voltage Reference Overview

The LM4041DYM3-1.2-TR is a precision micropower shunt voltage reference manufactured by Microchip Technology, housed in a 3-pin SOT-23 surface-mount package. It provides a fixed reverse-breakdown output voltage of 1.225 V at an operating current (IR) of 100 µA and 25 °C. The device features a typical temperature coefficient of ±20 ppm/°C and a wideband noise of 20 µVrms within the 10 Hz to 10 kHz frequency range. Operating specifications include a minimum current of 65 µA and a maximum current of 12 mA, with an industrial operating temperature range from -40 °C to +85 °C.

Voltage Reference Feature Summary

Bandgap reference design incorporating temperature drift curvature correction for stable accuracy across varying temperatures and currents.
Capable of tolerating capacitive loads without requiring an external stabilizing capacitor, simplifying circuit implementation.
Low dynamic impedance ensures consistent reverse-breakdown voltage stability under different operating conditions.

Voltage Reference Applications

Battery-powered equipment
Data acquisition systems
Instrumentation
Process control
Precision audio components

Voltage Reference Procurement Notes

Verify that the specific ordering suffix matches the required tolerance grade and packaging format. Confirm the manufacturer designation aligns with Microchip Technology specifications. Ensure the component meets the necessary environmental standards and package dimensions for the intended PCB layout before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a fixed 1.225 V reference is required in space-constrained designs utilizing the SOT-23 package. Consider the 12 mA maximum operating current limit and the 65 µA minimum current requirement during circuit design. Verify compatibility with the target application's temperature range and load regulation needs.

Voltage Reference Part Context

The LM4041 belongs to the LM4040/LM4041 family of precision micropower shunt voltage references. While the LM4040 offers fixed voltages of 2.500 V, 4.096 V, and 5.000 V, the LM4041 variant specifically provides a fixed 1.225 V output or an adjustable version. Both share similar low-power characteristics and package options.
